Zmnenfor FRED A.BA|| EY. firm/W4 attorney Patented Sept. 6, 1938 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to the ventilation of buildings, and specifically tostorm sash provided with ventilators.

One object of the invention is to provide a ventilator for a storm sashof such simple construction that it may be manufactured at a limited cost.

Another object is to provide a ventilator which will be entirely concealed from view when applied tothe sash and will not be exposed to external injury.

Still another object is to provide such a construction that the sash may be disposed in compact form for shipments from the factory without injury to the ventilators. I

With the foregoing objects in view, and others to be mentioned hereinafter, the invention presents a new and useful construction as described herein and claimed, and as illustrated in the accompanying drawing, it being understood that changes may be made in form, size, proportions and minor details, said changes being within the scope of the invention as claimed.

In the drawing, Fig. 1 is, a view, partly in section, showing the front side of awindow storm sash.

Fig. 2 is a side view of a ventilating strip, and Fig. 3 is a view of the same in longitudinal section, the handle being bent outwardly from the body'of the strip. Fig. 4 is a view similar to the view shown in Fig. 3 the handle being bent inwardly and disposed in line with the body of the strip.

Fig. 5 is a section on line 5-5 of Fig. 1. Fig. 6 is a sectional view of one of a combined ventilatorsupport and spacing-member, and Fig. '7 is an enlarged detail view on line '|1 of Fig. 1 showing an air passageway, a slot and a spacing-member in the slot.

Referring now to the drawing for a more particular description, numeral I0 indicates awindow storm sash provided with a slot I I opening on the bottom midway between its sides, and at I2 are indicated numerous air passageways extending therethrough to open on its sides and also opening on the slot I I.

Numeral I3 indicates a second slot which opens on the slot II and also opens on the front of the sash. At I4 is indicated a ventilating-strip provided with apertures I5 and also provided with a handle I6, this handle preferably being a part of the body of the strip I4, and adapted to be produced by forming an incision :1: approximately of U-shape in said strip and then bending the tongue-shaped portion outwardly to operate as a handle. I

The ventilating-strip thus described is disposed in the slot II and is adapted to have longitudinal sliding movements therein while supported by spacing-members I'l.

These members I1. discharge twofunctions, one

of their uses being to prevent undue contraction of the wood or fibrous material of the sash which forms the walls of the slot-II, and their other function being to support the strip I4 thereon for its sliding movements.

Since the storm sash for windows are exposed to rain and snow and to excessive sun-heat which might cause shrinkage or distortion of the side walls of the slot I I and thereby might prevent. free longitudinal movements of the strip I4, the use of members I1 is important to operate as spacingelements, and since the slot II opens on the bottom of the sash, these elements I I confine and prevent loss of the ventilating strips during shipments.

It will be understood that the tongue-shaped handles I6, before they are bent, are disposed in the slot II and are in protected position so that the sash may be shipped in compact position, and the handles I6 are not bent outwardly into slots I 3 to operative position until after shipments have been made from the factory.

The spacing elements I! may have any desired form to maintain the walls of the slot I I in spaced relation so that the apertured strip I4 may have free sliding movements thereon. In the drawings, the mounting for each spacer I1 is on a keeper I8. 7

Since the air passageways I2 extend outwardly, with a downward inclinatiomthis feature tends to prevent rain or snow from movinginto the slot I I.

According to the present construction, no metallic parts are exposed, and therefore no breakage of such parts may occur, and since very few metallic parts are required for operation, the device may be conveniently and economically produced.

I claim as my invention:

1. A window storm sash having a slot opening on its bottom, a plurality of passageways extending therethrough to open on the sides and slot of the sash, and a second slot opening on the first named slot, a plurality of spacing-elements in the first named slot, and an aperturedstrip in the first named slot adapted to engage the spacing-elements and having a handle in the second slot for disposing said strip with its apertures in register with said passageways.

2. A window sash having a slot opening on its bottom, air passageways opening on the opposed sides and the slot, and'a second slot opening on one of its sides and the first named slot of said sash, spacing-elements in the first named slot, an apertured ventilating-strip in the first named slot above the spacing-elements having a tonguemember normally disposed in the first named slot and adapted to be bent through the second slot for use in moving said strip to dispose its apertures in line with said passageways.
